    Depending on settings, they will only reset:

    A) After you drop 1-7 and the 8 ball, AND get all DELUXE targets
    or
    B) After you drop 1-7 and the 8 ball, then drain and begin another ball.

    Replying here, because Toyguy and I are working on the same machine.

    Quoted from BigAl56:

    No matter how switch 23 is configured the targets should always reset between players on a multi player game.

    Agreed. And yet it's not happening.

    Quoted from BigAl56:

    What you want to do is verify the expander is in fact activating between players. You can do this by observing the dummy lamp under the playfield that helps activate the expander. After the ball drains the game should light that bulb indicating the SCR is attempting to energize the relay, you should hear the relay click at the same time and then the reset coil should pull.

    The expander definitely is not behaving correctly between players. I'll let Toyguy elaborate, but I believe the bulb is staying on when it shouldn't.

    Quoted from BigAl56:

    One thing that comes to mind is replacing the expander bulb. You will want to do that with a new 555 lamp. Some times the 555 gets removed to do a quick swap on another lamp, other times it has failed, and it might even have been inadvertently been swapped out with an LED.

    In addition to trying a new bulb, we tried a brand new expander board. No change. So, while the expander isn't behaving properly, the problem appears to be coming from somewhere upstream.
